What Effect Does Heat Have On A Human?

• Core Temperature Ranges

98 to 99 Normal
99 to 104 Heat Exhaustion
104 to 110 Heat Stroke
110 to 114 DEATH
Brain damage starts at about 105.5 to 106
13
Human Body Generates Up to 50 degrees of Heat in
24 Hours How Does the Body Lose Heat?
RADIATION occurs when the air temperature is
lower than your body temperature
65
CONVECTION is heat loss to air and water vapor
around your body which must be lower than your
skin temperature
10-15
CONDUCTION is the transfer of heat from warmer to
cooler objects by direct contact
2
EVAPORATION is the release of perspiration
through the sweat glands on the skin surface
25
14
When the temperature around you is over 95
degrees.
RADIATION, CONVECTION and CONDUCTION stop
working
EVAPORATION is all you have left
Any clothing, especially protective type used by
racecar drivers, industrial workers and
welders MAKES the heat situation EVEN WORSE
15
NORMAL Blood  Circulation
Average human blood capacity is 5.6 liters or 6
quarts. Three circulation cycles
per minute
For normal heat loss, ¼ liter of blood is sent to
your skin surface per minute for cooling
BLOOD CIRCULATION for HEAT LOSS
When heavy perspiration occurs, 6 to 8 liters of
blood flow to your skins surface per minute for
evaporation. This is up to one-half of your
bodys normal blood supply.
Now your bodys brain, muscles, vital organs
are working on only ONE-HALF of what is normally
required.
16
What Are The Signs of Heat Exhaustion and Stroke?

• Heavy perspiration
• Fatigue Weakness
• Skin is cold, pale and clammy
• Muscle and body ache
• Headache
• Nausea
• Possible vomiting and collapse with or without
  loss of consciousness
• Skin is hot, dry and red
• Rapid heartbeat
• Confusion
• Loss of consciousness

Cause is high heat/humidity, loss of body fluids
and electrolyte imbalance (i.e. loss of sodium,
dehydration)
17
How the COOL SHIRT works

• The shirt uses conduction to cool the blood

• 50 feet of tubing on the front and back - 4
  cooling zones

• The shirt covers 30-40 of the skins surface
  with
• temperature-controlled cool water - 45 to 60
  degrees

• Perspiration and dehydration are greatly
  decreased

• Cool water transfers body heat 28 times faster
  than air
• Titanic Hot Tub 104 degrees
  Sauna 200 degrees
